local script:
local plr = game.Players.LocalPlayer
plr.Chatted:Connect(function(msg)
if game.Players:FindFirstChild(msg:sub(1,-3)) then
print(game.Players:FindFirstChild(msg:sub(1,-3)))
game.Players:FindFirstChild(msg:sub(1,-3)).Character.Humanoid.WalkSpeed = msg:sub(-2)
end
print(msg:sub(1,-3))
print(msg:sub(-2))
end)
output world_kiIIer 55
world_kiIIer is from print(msg:sub(1,-3)) and 55 is from print(msg:sub(-2)) why wont it print my name or change my speed?

i think you mispelled WalkSpee... or something else
you're forgetting about filtering enabled xd. you cant change walkspeed locally, server won't notice a thing
its not the server who changes it, u can change walkspeed using a local script. thats whats being done in exploits
